Epoxy as the internal insulation
Epoxy takes the place of oil as the internal insulation and winding impregnation. The advantage of this design includes:
- Reduced footprint with a compact design with up to 30% less height than the leading oil-filled designs
- High tensile strength which allows for mounting in any position including vertical, horizontal, upside down, or at any angle
- Environmentally friendly design eliminates hidden costs associated with traditional liquid-filled designs such as:
- oil-leakage problems
- oil filtering or testing
- construction requirements for a large installation space or dedicated support structure
Superior Design Features
SUPERBUTE Advantage: Superior primary winding design and extra creep distance ensure accurate, reliable performance in harsh conditions
SUPERBUTE instrument transformers are designed for quality and reliability with features engineered to withstand high voltage stresses and extreme environmental conditions, while delivering the highest accuracies possible, all within a compact design. The result is a reliable, long-lasting, easy to handle design that ultimately lowers total cost of ownership.

Lattice-type windings for voltage transformer
Originally patented by GE Vernova, lattice-type windings have precise controlled positioning and distribution of each turn to reduce maximum voltage stress within the winding. This unique design also minimizes the possibility of partial discharges within the winding. The coil configuration, and the outer electrostatic shields distribute steep voltage fronts across the coil to reduce concentration of stress.
Built-in surge protection for current transformers
A unique multi-gap type primary by-pass on current transformers 600 amps and below protects windings during line disturbances or steep current wave fronts. The gaps are factory adjusted to fire at 5000-7500 crest volts, thereby by-passing surge currents up to 100 times rated, which could otherwise result in excessive voltages across the primary winding.
High accuracy, extended range ratings for current transformers
The use of high accuracy instrument transformers with solid-state metering allows for improved billing accuracy and/or the potential to reduce inventory requirements. GE Vernova offers high accuracy and extended range ratings which meet the accuracy needed for these applications. Since introducing the first dry-type high-accuracy transformer solution in 1991, GE Vernova’s high accuracy product line has grown to a portfolio that includes a wide variety of voltage classes up to and including 69 kV.
Compact size & mounting flexibility
SUPERBUTE transformers require up to 30% less height and up to 40% less floor space compared to the leading oil-filled designs, and can be mounted in any position. This allows substation design flexibility including mounting on a substation steel structure or a pole.
Extra creep & strike
Even with 30% less height, standard units can be used in environmentally severe conditions and in high altitude (10,000ft) applications. Station class units have creep distances that exceed the requirements for even the next-level voltage class.

Encompass wide range CTs are designed for commercial and industrial applications. Encompass CT’s substantially reduce inventory, complexity and improve standardization for meter shop operations, particularly when used with GE Vernova’s kV2c FITZALL™ transformer rated meters.
Application Overview: Secondary Metering with Current Transformers
Encompass and RevenueSense CTs provide flexibility for commercial and industrial applications, indoor or outdoor service and bar-type or window-type configurations.
Redefining the Test Limits
Traditionally, CT accuracy is tested at:
- 10% of rated current (light load)
- 100% of rated current (full load)
- With a rating factor between 1.0 and 4.0.
With GE Vernova Encompass CT’s, the 0.3 accuracy class is extended by changing the test points to:
- 4% of rated current (light load)
- 40% of rated current (full load)
- With a typical rating factor of 4.0
Standard CT Test Limits
Wide Range Designed for CL20 Meter
A rating factor of 4.0 means the Current Transformer meets rated accuracy at up to 4 times the rated primary current. Thus, the output on a 5 Amp CT secondary can be used up to 20 Amps if a rating factor of 4.0 is assigned to the CT (4.0*5A = 20A). This pairs the CT output range and the Meter input range when used with a CL20 transformer rated meter, maximizing the performance potential of the system.
Encompass Test Limits
Results and Benefits
The 4% and 40% test points in combination with a high rating factor of 4.0 means 1 Encompass CT can equal or better the performance of both higher AND lower ratios.
The 500:5 Encompass unit when compared to a 200:5 standard CT has equal to or better test results at all points included even low currents and is available at an equivalent price. This comparison holds true across several other standard CT ratios, meaning one Encompass CT can functionally replace up to eight other standard ratios, allowing for an inventory reduction of up to nearly 90%.
Encompass CT vs. Standard CT
To demonstrate the advantages of upgrading to an Encompass CT,
let’s compare a JAK-0W 500:5 Encompass CT to a JAK-0C 200:5 standard CT
Physically, the JAK-0W 500:5 Encompass CT:
- Is lighter
- Has the exact same mounting plate
- Has the exact same terminal locations
- Has the exact same window size
Electrically, the accuracy of a JAK-0W 500:5 is equivalent or better than the accuracy of a JAK-0C 200:5 across all test points. This can be looked at two ways:
A 500:5 Encompass CT has ±0.3% accuracy from 200A to 2000A, compared to a standard 200:5 CT which has a ±0.3% accuracy from 200A to only 800A. Both CT’s have ±0.6% accuracy from 20A to 200A.
The 500:5 Encompass CT has equal to or better accuracy rating across the entire 20A to 2000A range. It is important to note that accuracy class only defines the “tolerance of error” allowed in a CT. Actual test results are also an important factor when evaluating CT’s. At a typical burden of B-0.1, the Encompass CT test results slightly outperform a standard CT, even at the lowest test amps. All Encompass test results are well within the IEEE limits.
* Tested Accuracy Class values shown are for illustrative purposes only, and not a guarantee of performance. Actual results may vary, within defined test tolerances.
